Brief Introduction
MG970 is a multi-frequency and multi-satellite RTK survey system called the
pinnacle device of integrated RTK. It has higher integrated body, and makes a
breakthrough to solve the various problems in the RTK device design and
manufacture. MG970 also has stunning accuracy, stability resistance, strong
compatibility and environmental adaptability, the entire device is more portable,
user-friendly and reliable.
Each mainframe of MG970 built a four-feed GNSS antenna with zero phase center,
with P307 multi-frequency and multi-satellite board, full-band UHF radio transceiver,
GPRS \ CDMA network communication module, Bluetooth wireless transmission
module and Micro SD memory expansion module. Using industry-leading ARM
Cortex- M3 32-bit processor designed for the mainframe control system, and it
provides receiver outstanding computational performance and exceptional system
response to events.MG970 combined with multifunction buttons and a high-resolution
OLED screen, it can complete intelligent operation of the mainframe, can be viewed
the state of the receiver chain and data, can be set on the receiver, select receiver
mode, data link mode, the liberation of the hand book, and improve work efficiency

ⅠMG970 mainframe
In this chapter, it will show the detailed information of MG970, such as appearance,
interfaces and some basic operation.
The mainframe of MG970 is a flat cylindrical, 100mm in height, 191mm in diameter.
The front side is a LED screen, 2 functional buttons and 3 indicators. The back side is
a battery compartment.
The bottom of the receiver is some interfaces. They include a radio antenna interface,
a GPRS antenna interface, a 5 pin external power interface and a 7 pin RS232/USB
interface.

ⅡBasic operation of MG970
In this section, we highlight the basic operation of MG970. It includes powering
on/off, checking work station, changing work mode, self-checking. All of these
basic operations are simple and easy. But they are very important
2.1 Power on/off
This is the first step to use MG970, it’s very easy to operate. Below we will explain in
detail how to power on/off the mainframe.
2.1.1 Power on
When the receiver has battery, keep press power key for some seconds.
Fig 2-1 Power on page
About 5 seconds later, the buzzer will call three times, then the initialization is
completed and you will enter into the main page.
Fig 2-2 work mode: rover, base, static
2.1.2 Power off
Keep press power key in the state of powering on until enter into another menu. It
shows as follow:

Then press function key to select. Switch to the “shut” icon, then press power key to
confirm. The mainframe will be powered off.

2.2.2Switch woke mode
When we get a receiver, we should switch work mode first, it includes base, rover,
and static. Keep press power key in the state of powering on until enter into setting
menu. Then press the function key to switch to “mode”, and you can press the power
key to enter into the mode selection menu. Select the one you want to use, then press
power key to confirm.

2.2.3Switch datelink and difference type
In the main page press the power button to enter the setup menu, press the function
key to switch to the "difference", then press the power button to enter data link
selection menu (Figure 2-6). You can switch directly to the built-in radio, GPRS,
external data link.
Fig 2-5 date link selection menu
If you choose to use the built-in radio, the radio will enter the Channel Setup menu
(Figure 2-7). After successfully entered the channel, the mainframe will switching to
the differential format menu.
Fig 2-6 ratio channel selection menu
After you select a differential format (Figure 2-8), you can switch between RTCM3.0,
RTCM2.3, CMR, ect.
Fig 2-7 differential format selection menu
2.2.4 The rover mode
In the rover mode, after you power on the device the date link is disconnected, you
10 / 25
need to manually set the date link. When the device received satellites normally, the
display will show state as in Figure 2-9, the icon indicates the data link is radio
and the channel number is 1.
Fig 2-8 rover station work mode
When the rover station receives the difference data , the icon above the display
will flash, indicating that the device receives differential data correctly (Figure 2-10).
Fig 2-9 rover station work mode
2.2.5 The base station work mode
1、Starting the Base
In the base mode, after you power on the device the date link is disconnected, you
need to manually set the date link. The base station can be set to start automatically or
start manually.
If start mode is automatically start, when the mainframe received the satellite and
reached the conditions, the base station will start automatically and transfer
differential dat.
If start mode is manually start, in the main menu press the power button to enter the
base station start menu (Figure 2-11), and you can choose to use the coordinates of the
last time to start base station. It could repeat a station in this way.
